This invention refers to a new construction of gas cooker, the noveltyof which is based on the arrangement of a support for the burner on theframe of the gas cooker, on the one hand, and on the other hand theinvention relates to a special construction of the burner itself. I I IAccording to this the burneris arranged interchangeably in a supportwhich can easily be taken out of the gas cooker or frame. This is of aspecial advantage in cleaning or renewing any part of the burner, as theparts can be easily removed or replaced as desired.

The support receiving the burner is interchangeably arranged on the gascooker in such a way that one end of a slide is formed into a ball whichis inserted into a double bearing, fixed to the gas cooker, and in sucha way that it may be swivelled in any plane,

while the opposite end of this slide is fastened simply on the gascooker either directly or indirectly with intermediate gear bearing arm,being detachable, so that the supporting-slide may be removed from thegas cooker immediately either with the burner or without. The burnerwill give a fan like cooking-flame on account of the specialconstruction and arrangement of each-part to the other, which forms aninner and an outer flame, giving a broad fan like cooking-fiame,

or through interchanging in taking off or exchanging the upper burnerlid, a coneshaped or wedge-shaped flame will be produced. a

Fig. 3 being a top view of the distributor plate 17,

gig. 4 a similar view on a smaller scale,

Fig. 5 a vertical section through the burner proper.

Fig. 6 is another construction of the burner.

Figs. 7 and 8 are single views of the same,

Fig. 7 being a top view of the plate.

. Fig. 8 is a similar view of the multiplied form of distributor on asmaller scale.

.Fig. 9 shows a sect-ion through another construction of the support,and s Fig. 10 is a top view of the same.

On the frame 1 of the gas cooker is secured the double bearing 2 whichreceives the pin 5 of the gas cock 6 at the outer plane; the gassupply-pipe 11 being in connection with gas cook 6 is loosely fitted inan extension of the fork bearing 9, and at the same time is interchancable with the gas cook 6 after loosenin t e screw 5 on pin 5.

he supporting slide 3, 7 is interchangeable and, for this purpose, thearm 3 is formed into a ball 4 at one end, which forms a ballbearing inconnection with the inner half of the double bearing 2, and thus allowsa movement of the supporting-slide with the burner.

Arm 7 of the supporting slide 3, 7 is situated in the fork-bearing 9,and the supporting slide is secured ab e pin 10.

In the middle of the supporting slide 3, 7 a circular hole 12 has beenprovided for receiving the burner 8 with slots 13 for leading thelateral pin 8 through.

The burner 8 which is open at the bottom and stands vertically isinterchangeably situated in a hole 12 of the supporting-slide 3, 7 andis provided with a circular collar 8, and under the same is providedwith a lateral pin 30 8 which in connection with the circular collar 8resting on the supporting slide 3, 7 formsa bayonet joint for the burner8. The burner 8 can also be firmly connected with the arms 3 and 7,whereby the interchangeability is se- 5 cured owing to the two parallelsupporting arms 3 and 7, lying in a longitudinal direction.

According to Figs. 9 and 10 the central section of the supporting slide3, 7 with the circular hole 12 is connected with ribs 14 acting assupporting arms, which are exchangeable in an adjustable way or thesemay be firmly connected with frame 1 of the gas cooker or with theheating-plate. The under part of the burner 8 is provided with a rim 12which is designed to receive the overflow while cooking and will serveto keep the burner clean.

The burner 8 is constructed in such a way by means of an extract- 7 asto form an inner and an outer burner independent of each other, andeither acting as cooking-burner or heating-burner. According to Figure 1of the drawings the burner-lid 17 which is put on the burner head 16 isprovided with holes in order to obtain a fan like cooking flame. At thesame time an inner burner is also formed in such a way that a plate 19,or the perforated hood 20, which are situated around the mixing-pipe 18,cover the mixing-space 21. Plate '19, Fig. 5, and hood .19 are arrangedinterchangeably. If the burner-lid 17 is removed the flame may be lit atthe inner burner, when it burns, forming a cone-shaped or wed e.- shapedflame, which will burn vertical y. The plate 19 covering the lower partof the mixing space is situated on the periphery of the burner pipe bymeans of fingers at 19,

and. the lid' 17 in Figures 6 and 9is conically inclined upwards to thecentre (Fig. 9). I In the burner lid 17, as well as in plate 19,

or hood 20 which are situated inside the burner-head there are slittedopenings 22 from the edge towards the central axis however not reachingquite as far as the centre, which serve or-forming the wedge-shapedheating flame which w1ll burn vertically. Owing to the specialarrangements of these slits 22, a distributor-plate 23 is formed onburner lid 17, plate 19 or hood 20.

The hood 20 may also be formed so as to be able to exchange the innerparts of the burner easily, into a case 24 and a plate 19 fixed into thesame, (Fig. 5).

' According to Figure 6 the burner is constructed in such a way that inorder to change the form of the flame only the upper lid of thecooking-burner 17 has to be removed. For this purpose aninterchangeable-lid 23, is used which is provided with slits 22 toproduce a cone-shaped or wedge-shaped flame, which will burn verticallywhich plate is inserted interchangeably as a heatingburner on theburner-covering 16 (see Fig. 5)

between the plate 19 and the lid of the cooking-burner 17, whereby theouter edge 26 is constructed as burner-head, and also forms at the sametime the burner head for the lid 17 of the cooking-burner.

The plate 23 is provided with slits 22 for the passage of the gas, andmay be situated interchangeably on the extension 26 of theburner'covering 16, under the intermediate lid 25, thus forming aheating-burner.

What I claim is:

1. A gas cooker composed of independent and means for supporting aburner inter-me dlate said arms.

3. A gas cooker in accordance with claim an adjustable support at theother end.

7 A structure in accordance with claim 6 in which the supportmg memberhas an opening for the detachable support of a burner. v v v 8. A cookercomposed of independent sections adapted for use as either a cookingburner or a heating burner, a removable hood, and a plate, the twolast-named elements being interengagingly related, and a lid, the latterbeing provided with openings,

to produce a wedge-shaped flame.
